Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed May 31. 1907. Serial No. 376,574.

T 0 all "whom it may concern:

Be it known that I, HERMAN J. Gnnnson, a citizen of the United States, residing at the city of lVausau, county of Marathon, State of isconsin, have invented certain new and useful Improvements in Dricrs, of which the following is a specification.

This invention relates to improvements in driers.

My improved drying apparatus is especially designed by me for drying clay products, such as brick, tile, or the like, although it is adapted for use for other purposes and in other relations where drying is done ona large scale.

The main objects of this invention are, First, to provide an improved drying apparatus for the operating of which a minimum amount of labor is required. Second. To pro vide an improved drying apparatus in which very little heat is wasted. Third. To provide an improved drying apparatus which is very economical to install and operate. Fourth. To provide an improved drying apparatus in which the danger or liability of loss by fire is reduced to a minimum. Fifth. To provide an improved drying apparatus which has a very large capacity, that is, one in which the articles may be very rapidly dried.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the object of my invention by the devices and means described in the following specification. I y

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, "forming a part of this specification, in which Figure 1 is a plan view of an apparatus embodying the features of my invention, the parts being shown mainly in diagrammatic form. Fig. 2 is a detail perspective, showing structural details of the drying cars. Fig. 3 is a detail cross section taken on a line corresponding to line 33 of Fig. 1, looking in the direction of the little arrows at the ends of the section lines. Fig. 4 is an inverted detail of the steam pipes. Fig. 5 is an enlarged detail section taken on a line corresponding to line 5-5 of Fig. 2 and Fig.

6 is an enlarged section showing details of the steam pipes.

in the drawing similar letters of reference refer to similar parts throughout the several views.

The accompanying drawings are intended to be merely illustrative of the invention, no attempt having been made to show the parts in proper proportion or the full structural details thereof.

Referring to the drawing, 1 represents a drying track. I preferably provide a series of these, two being illustrated in the accompanying drawing. At each end of the drying tracks I provide transfer tracks 2, and at one side a main track 3 leading to the mill or to the burning kiln. Suitable turn tables 4 are provided at each end of the drying tracks. At one end' of the drying tracks I arrange a tunnel 5, which is connected to the tunnels 6 under the drying tracks. The steam pipes ll are arranged at the top of these tunnels, as is shown in the drawing. Above the steam pipes I preferably arrange a deflector 7 extending from end to end of the drying track being open at each side for the passage of the heated air from the tunnels.

The steam pipes 11 are preferably connected by suitable headers as 12, the headers being connected to the supply pipe 13. Valves 14 are interposed between the supply pipe and the headers so that the steam may be cut oil from either one or both of the drying tracks, as desired. The steam pipes 11 are preferably connected at intervals by cross pipes 15, the cross pipes having valves 16 therein. To the rear of and adjacentto these cross pipes are valves 17. This arrangement enables the controlling of the pipes so that the circulation maybe only through a part of the system, as desired. The cross pipes and valves are arranged at intervals along the drying track, corresponding in length to the length of the drying cars 18, so that should the track be only partially filled with cars, the heat is delivered only to that portion of the track in use.

The drying cars 18 are adapted to receive the articles to be dried, being provided with suitable shelves or trays for that purpose, and being skeleton-like in form to admit the passage of the heated air upwardly therethrough.

The roofs 19 of the cars are preferably adapted to overlap when the cars are arranged end to end. on the drying track to form a continuous roof. To accomplish this, one end of the car is preferably provided with a drop ledge 20, which projects under the end of the roof of the adjacent car, as clearly appears in Fig. 2. The roof of each car is preferably provided with a ventilator 21 to cause a draft upwardly from the hot air tunnel. The sides of the car are preferably closed by means of curtain walls 22 of suitable material adapted to be rolled or otherwise held out of the way when desired. The corner posts 26 of the cars are preferably provided with gaskets or packing strips 24 to form a tight joint when the cars are brought end to end. These gaskets or packing strips also serve as buffers. Guide plates 25 are provided for the corner posts at one end of the cars, the plates being adapted to guide the adjacent car into place and to assist in making a tight joint.

By thus arranging the parts, the articles to be dried, as bricks or the like, may be loaded on the cars directly from the machines and run out on the drying tracks, and the steam turned on to the track or the portion of the track. occupied. The hot air arising from the hot air tunnel passes upwardly through the cars, as stated. By this means I avoid the necessity of drying sheds and of handling the brick or other articles.

When it is desired to fire the brick or tile or the like, the cars may be run directly to the kiln after the articles are suitably dried.

I am by this apparatus enabled to dry the brick very rapidly with a minimum amount of fuel and-labor. The equipment is also very economical as to its first cost and is very durable. Another advantage is that the danger of loss by fire is reduced to a minimum.

I have illustrated my improved drying apparatus conveniently and diagrammatically, the drawings being intended to be only illustrative rather than to show structural details.
